I drove my way to work today with Spotify mobile app, and the playlist Discover weekly was already updated on Android (126.96.36.1999 BETA).
However the Linux Desktop version (1:188.8.131.52.g3b776c9e still was showing the old one.
After turning it off and on again second time it worked.
Is there some kind of caching ? What makes it refresh.
Beside, yesterday I found that, by adding playlist through Web API, in the Linux Desktop it presents new playlist called "Loading..." , only after I turned off and on the program it was shown properly.
If it will help, I use SOCKS5 proxy at Linux Desktop app, so it might be relevant for refreshing issue.
